Unfortunately, my experience wasn't a good one. I started off by cleaning the tires with DA, and ran some practice laps to scrub them in. I didn't run a lot on them [currently only have one battery], but they felt good, so I repeaked by battery, tried them out with some Paragon for a few more laps, then cleaned them with DA and treated with Paragon for the first qualifier.

A buddy of mine followed the same prep and we were in the same qualifier. Off the tone, the car was very fast, but this only lasted 6-7 laps. For the 10-12 laps after that, it was a big struggle with oversteer [losing lots of time], then, strangely, the handling balance started to return and the lap times started to come back, but nothing as fast as the first 6-7 laps. My buddy and I [running different chassis and different driving styles], commented on the SAME laps when rear grip went away, and again when grip seemed to return.

For the second qualifier, I thought maybe the Paragon wasn't agreeing with the tires, so I only cleaned with DA and put the car on the track. The car started off with a slight bit of oversteer, but felt alright, early in the run. Toward the middle of the run, the car alternated between super loose and barely making a corner depending on the lap, and then settled down again the last 2 minutes or so. My buddy switched to some Sorex tires and laid down a relatively solid run.

For the third qualifier I bolted on some used CS22's just to get a consistent qualifier in, which I also raced in the main.

I bought a set of mediums as well, but with the inconsistent handling the softs gave, they stayed in the package all day.

I'll give these tires a try on the outdoor asphalt track, and may give the mediums a run on the carpet just for testing, but so far, I'm not very satisfied.
